X³ = 1/8
Take the cube root of both sides.
∛x³ = ∛(1/8)
Since x³ has 3 of such x multiplying each other so we bring out 1 of the x from the cube root sign as discussed.
x = ∛((1/2)*(1/2)*(1/2))
We bring out 1 of the (1/2) out of the cube root sign as well.
x = 1/2
So the answer is the first option. 1 over 2.
I hope this helps.

Answer:
3x^2 + 3 --> 6, 15, 30, 51
2x^2 - 1 --> 1, 7, 17, 31
x^2 + 2 --> 3, 6, 11, 18
Step-by-step explanation:
Let's start with the first equation; 3x^2 + 3
Substitute 1 (the first digit in a sequence) for x.
3(1^2) + 3
3(1) + 3
3 + 3 = <u>6</u>
3(2^2) + 3 Then the second digit.
3(4) + 3
12 + 3 = <u>15</u>
Since the two numbers we have so far are 6 and 15, there is only one sequence this could match. 6, 15, 30, 51.
2(1^2) - 1
2(1) - 1
2 - 1 = <u>1</u>
This equation represents 1, 7, 17, 31.
These same steps apply to the other equation as well.
1^2 + 2, then 2^2 + 2, then 2^2 + 2, and so on. (But we don't need to do extra work to figure that out.)
If the test is a major grade ( 60% of final grade) then around 73-75 but if the grade is worth a daily grade (40% of final grade) 78-82
Answer:
All of them would be under $65
